Normally a wastewater treatment plant discharges its effluent continuously. Consider for a moment what would happen if the effluent were held for three days prior to discharge. Five things would happen:
1. The effluent in the holding pond could be sampled and tested every three days. If the results of the testing were satisfactory, the contents of the pond could then be discharged.
2. The effluent in the pond could be returned to the treatment plant during periods of low flow. This would provide "a little snack" for the microorganisms between the periods of high flow. In addition, the quality of the effluent would be improved.
3. The effluent could be returned to the plant for further treatment if it did not meet the effluent standards. This would provide a "second chance" at compliance instead of submitting a report of a violation.
4. Samples would need to be collected and tested every third day rather that every day thereby reducing the operating costs.
5. The environment would be better protected.
